Lume Cubes Twin Pack

The Lume Cube is a tiny 1.5inch cube light that can be used anywhere as an additional light source or flash and is waterproof down to 33 metres (100 feet). You can use more than one, for multiple light sources. Here we’re looking at the twin pack, which includes two Lume Cubes.

Features and Handling

A single 1500 Lumen LED gives a 6000K colour temperature, and 150 Lux at 3m. There are two buttons on the top of the Lume Cube, and you can dim the light from off to full power, with 10 steps. Simply press the button to change the power output. The cube is 1.5inches in size and portable with a built-in rechargeable lithium-ion battery.

The compact size and tripod socket means you can mount the light on any tripod – or using an adapter, the top of your camera. An adapter is available to let you attach the Lume Cube to your smartphone, as a light source. There’s also an optional diffuser kit available.

Controlling the Cube using the two buttons on top:

Left Button

– Turns on the constant video light.
– Click multiple times to cycle through the 10 brightness settings.
– Hold for five seconds to shut down the cube.

Right Button

– 1 click activates the Bluetooth.
– 5-second hold activates the optical sensor.
– 1 click turns off the constant video light.

The Lume Cube is very well made, with a solid metal frame, and plastic back. The microUSB charging socket is covered with a small screw that you need to unscrew in order to charge the light. If you want to keep the Cube protected from water, then this needs re-attaching. After continued use of the light, it can get warm, but this did not appear to cause any problems.

The performance section is where we look at the image quality possible with the light. Additional sample photos and product shots are available in the Equipment Database, where you can add your own review, photos and product ratings.

The Lume Cube is extremely easy to use, with two buttons on top of the light. You can press the left button to turn the light on and use it as a constant light, which makes it easy to see the effect of the light straight away. Pressing the right button activates Bluetooth, and holding this for 5 seconds enables the use of the Cube as a slave flash. To charge, you simply unscrew the USB cover and connect the provided microUSB cable.

Even if you’re kit bag is full of other stuff, you can still squeeze in a couple of Lume Cubes, and providing you have room for a couple of compact tripods, then you can use the Lume Cubes anywhere. In this shoot, I set up one on a magnetic tripod, and another on a bending tripod that I attached to a metal grill.
